Set within the vibrant dancehalls and low-life hang-outs of 1940s Paris, ambitious young actress Jenny, her covetous, piano-playing husband/manager Maurice Martineau and their devoted confidante Dora Monier attempt to cover one another's tracks when a sexually ogreish high-society business acquaintance is murdered. Enter Inspector Antoine whose seasoned instincts lead him down a circuitous path in this classic whodunit murder mystery.
